Abstract

Provided is a method with which a separator-integrated electrode having a shutdown function can be easily produced using a water-insoluble polymer. The method for producing a separator-integrated electrode disclosed here includes the steps of: preparing a coating liquid in which a water-insoluble polymer is dissolved in a mixed solvent containing a good solvent for the water-insoluble polymer and a poor solvent for the water-insoluble polymer and in which polyethylene particles are dispersed; coating the coating liquid on an electrode; and vaporizing and removing the mixed solvent from the coating liquid coated on the electrode. A boiling point of the poor solvent is higher than a boiling point of the good solvent. A porous separator layer is formed by removing the mixed solvent through vaporization and thereby forming pores.
